Species of the day

365 days, 365 species

We published a fact file on a different species every day during 2010 to celebrate the UN's international Year of Biodiversity.

Each species we explore has been chosen and written about by a Museum scientist. All the information, images, facts and stories contained within the species files has also been provided by them.

Species by category

Some scientists chose to write about species which are part of their research. Others picked species which are particularly interesting because of their value to science, economic impact, or because they show the evolution of interesting types of behaviour.  

Some of the species featured were collected and described for the first time by Museum scientists or are found in the Museum's collections. And some are endangered because of climate change, loss of habitat, or threats from other invasive species. Studying them reveals the importance of maintaining biodiversity in Britain and around the world.
